@tm-up Hi! Yes, topology parsing has been asking for refactoring for a long time ;-)
Can you post/share sysctl -qn sysctl kern.sched.topology_spec ?
Also, cpu-topology script has nothing to do with Windows 11 problems: if Windows 11 guest requires specific CPU topology, you can use cbsd vm-cpu-topology-tui to create custom bhyve topology and apply it via cbsd jconfig or cbsd jconstruct-tui or cbsd jset (vm_cpu_topology options). Or use bhyve_flags to pass cpu-related bhyve options as-is.
AFAIK, Windows 11 requires for TPM ( passthru added in development CBSD version, but bhyve_flags also usefull ). TPM emulation via https://github.com/stefanberger/swtpm still WIP.
In addition, if you use virtio drivers on Windows, you may need to patch the bhyve, checkout https://github.com/cbsd/cbsd/tree/develop/upgrade/patch/iov-14.0 , e.g.:
cp /usr/local/cbsd/upgrade/patch/iov-14.0/patch* /usr/src/usr.sbin/bhyve/
cd /usr/src/usr.sbin/bhyve
patch < patch-usr-sbin-bhyve-block_if.h
patch < patch-usr-sbin-bhyve-virtio.c
make clean
make
make install

Hi Oleg!
Many thanks for the quick response and the pointer to your virtio improvement. I will look into this.
I have played with the cbsd vm-cpu-topology-tui, I have tried 1/1/1 and 1/1/2 and 1/1/4. None worked.
Then I used the BypassTPMCheck hack to avoid the need for a TPM module.
Here is the output of sysctl -qn sysctl kern.sched.topology_spec:
